Inflammatory bowel disease (IBD), as the name implies, refers to inflammatory condition of the bowel or gastrointestinal (GI) tract. It is a group of disorders characterized by inflammation of bowel or any part of the GI tract. Though the exact cause of the condition remains unknown, the genetic and non-genetic or environmental factors are thought to play a part. All these factors may impair the normal functioning of the immune system and the body’s defense mechanism attacks body’s own tissue causing inflammation of the mucosal lining.
Though IBD is an umbrella term for group of diseases, the two major sub-types include ulcerative colitis and Crohn’s disease. In both the conditions, the inflammation may persist for longer time and have waxing and waning course in severity as well the intensity of disease.
